Hello -I've got a KitchenAid Side by Side (KSSC48QMS02) that is overheating.I noticed one day the door seal was hot and so was the stainless in front between the freezer and fridge.Temps were +10 from where they should be and I felt a lot of heat up top.I looked around up top and for how hot it was up there I couldn't believe the cooling fan for the coils wasn't on.I decided to experiment, I put a small fan up there on the coils and it was working great within an hour.the odd thing is, I came back to check again a few hours later and the built in cooling fan was working I shut my extra fan off to see what would happen and a few hours later, hot and same problem.\Luckily, while i troubleshoot, the extra fan keeps it running great.Any ideas ?Thanks !

Probably a bad condenser fan motor or a bad main board. It should run when the compressor runs. Check for 120 voltst at the condenser motor when the unit is cooling. See the tech sheet for the KSS below:
